Square carbon fiber tube, outer (20x20 mm.) - inner (18x18mm.) - Length 1000 mm.

Square tubes, also known as carbon fiber box sections, are optimised for high-performance strength and stiffness. With in-built radiused corners and flat sides, they are ideal for building support systems, lightweight frames and structures.

Carbon fiber square tube mesh view, made entirely of high-quality carbon fiber. It is real carbon fiber, pressed and cured in the oven. With constant thickness, very high hardness, and very little weight. If what you are looking for are the benefits of the carbon tube, this is your product. If you need a tube with other lengths, diameters or thicknesses, do not hesitate to contact us; we can manufacture it.

CHARACTERISTICS

• Length: 1000mm. (Tolerance ± 10mm.)
• Outside diameter: 20x20mm. (Tolerance ± 0.2mm.)
• Internal diameter: 18x18mm. (Tolerance ± 0.2mm.)
• Weight: 456gr. (Tolerance ± 5gr.)
• Orientation of the fibers: Bidirectional

Since these tubes are made of 100% carbon fiber and with a very constant thickness, they are perfect for precision or structural work.

Our square or rectangular tubes allow easy assembling for example, to manufacture machine beams, composite tools or composite structures that are light, rigid, resistant and stable (coefficient of thermal expansion close to 0).

You can choose from our range of standard tubes or contact us for custom profiles. The profiles are designed and manufactured according to your needs with the support of our composite experts. The dimensions are limitless.

Our square tubes are manufactured in Pultrusion and Pullwinding in our China factory in order to guarantee impeccable manufacturing quality. For certain productions in small series or very large dimensions, we will suggest the use of complementary manufacturing processes.

LIJIN carbon fiber offers square, rectangular, hexagonal octagonal carbon fiber tubing in various sizes for different applications. All our lightweight and high-strength carbon fiber square tubing is made from premium quality unidirectional carbon fiber prepreg fabric and 3K twill/plain carbon fiber prepreg fabric.

Ultra-strength square carbon fiber composite pipes can be widely used as aircraft frames, trusses, agricultural drones, or other special applications. We can offer 1/4, 3/4, or 1-inch square carbon fiber tubes, or custom-made, shaped composite tubes based on different applications.

In general, the carbon fiber tubing is made from Toray T300 100% real carbon fiber prepreg fabric. Of course, we can also choose high modulus Toray T700 or T800 carbon fiber fabric to meet clients' special requirements. Additionally, Colored Kevlar or forged carbon fiber tubes can also be offered.

We produce round, square, rectangular, oval, elliptical, octagonal, hexagonal, and custom-made carbon fiber tubes and profiles. Die cost can be returned based on order quantity. Please contact us freely for more details.
